I am setting up a new iPhone 13 using iTunes (El Captian). After the data transfer began, iTunes said my the device was disconnected. After more than an hour, the iPhone still says Backup in Progress. Is it? Or, do I need to shut everything down and try another method to transfer my data?
Please try again.
